Anthropic just dropped Claude Sonnet 4.5, an AI model that proudly burned 30 continuous hours writing about 11,000 lines of code to create a Slack/Teams wannabe chat app — all without bathroom breaks or existential dread! This super-busy bot outplays its predecessor, Opus 4, which could only handle a mere 7 hours of solo grind back in May. Anthropic brags Claude Sonnet 4.5 is the 'best model in the world' for AI coding supremacy, clearly aiming to crush the competition like your inbox on Monday morning. Who needs sleep when you’ve got AI coding marathons?
